The animation looks good. Impressive. The idea of learning another language like this is great. I don't know if this particular series is a good example... Maybe I am a little bit slow, but it doesn't seem to be for beginners. Maybe this one for someone looking to perfect their knowledge...
Anyway, I am a grown up person, with a job and pay and I know how much it takes to make something like this, that's why I don't look for free options, but what I definitely don't like, is how many things are becoming a subscription service. I really don't like the idea of automatic payment. If I see something that catches my attention, and would like to see more, then paying to see it makes sense. Like I would pay if I wanted to see a movie in a theater. Otherwise I completely lose interest. Quality is always more important than quantity to me. But that is just my opinion.
